Hello fellow Rhino and grasshopper users,
I have a question how to approach my desired transformation of a 3D brep.
As shown in first picture I have a 3D brep model in rhino3D (right side) of a car part, now this shape is very smooth and detailed.
I wish to create a copy of this shape but then simplified and geometric.
I have tried extracting isocurves simplifing those and then rebuilding a surface with those lines (left in the picture) this is already a bit in the right direction, however this is not really what I desire.
I prefer two main parameters in the eventual grasshopper script. First would be the ‘roughness’ of the generated shape.
Second that it always creates a shape which is ‘wider’ than the original surface, so that the new shape doesn’t intersect with the original one (when I just simplify the curve is will intersect as seen in the second picture).
I hope somebody can give some tips or make a small sketch in grasshopper to teach me how they would approach/solve this problem.
I attachted the rhino3D file with the brep and the simple grasshopper script which was made in order to get the simplified version of the brep.
Thanks in advance,
Rob
